Profile: As part of the Rockies retooling process, Tyler Chatwood is now a part of Colorado’s organization after the Angels traded him for catcher Chris Iannetta. He struggled with the Halos in 25 big league starts last season, but he showed off his velocity and developing curveball. The ground-baller is still just 22-years old, and as he was rushed through the Minor Leagues, he could use another year in Triple-A to work on his approach and command on the mound. Don’t draft him unless you have an extra spot in a dynasty league, especially now that the Rockies have about fifteen options for their final two rotation spots. (Zach Sanders)

The Quick Opinion: Chatwood struggled in his Major League debut, but he was very young and rushed through the minors. He will likely get a good deal of time in the Minor Leagues, so he’s not an option unless you’re willing to wait a year or two for a pitcher without top starter upside.

Profile: Young Tyler Chatwood’s debut season with the Rockies was a forgettable one. Both out of the bullpen to start the season and as a starter late in the season, he struggled to miss bats (5.4 swinging strikes, 14% strikeouts) and surrendered too many free passes (11.2% walks) to have any success. At the season’s conclusion, Chatwood was sent to the Arizona Fall League to continue his development, but less than stellar results have Chatwood on the outside looking in on the Rockies’ rotation to begin the 2013 season. It's unlikely Chatwood will have any fantasy relevance in 2013, unless he can find a way to crack the rotation, perhaps by taking better advantage of his gas (~94 mph) by refining his secondary pitches. So far all he's been able to do is keep the ball on the ground (56.3% ground balls in 2012) -- and that's not enough. (Alan Harrison)

The Quick Opinion: Chatwood got grounders and did nothing else right for his new team. He'll have to do much better to beat out the other five hundred mediocre starters that will enter camp with the Rockies in 2013.

Profile: The Rockies are constantly in need of starting pitching. So when someone like Chatwood comes along and posts the fourth-best single-season ERA- mark in team history (minimum 100 innings pitched), people stand up and take notice. And they did. With Chatwood only 24 years of age this coming in season and still under control for a few more years, suddenly the Chatwood-Chris Iannetta deal is looking like a win-win. The caveat is that Chatwood might not have the stuff to back up his shiny 3.15 ERA from a year ago. The margin for success for any pitcher who doesn't pile up a lot of strikeouts is razor thin, and so it will be for Chatwood. His 6.8% swinging strike percentage was well below the league average of 9.3%. Chatwood simply wasn't able to get hitters to chase out of the zone as much as you would like to see. This led to a very high contact percentage, particularly within the strike zone. Of the 145 pitchers to toss at least 100 innings last year, only 10 pitchers had higher Z-Contact%'s than did Chatwood. That's perfectly fine when you're keeping your walk rate low and stranding more than two-thirds of the runners who reach base, but any slight uptick in either rate and Chatwood is going to appear a lot more mortal. He's not a closed book yet though, and if he finds a way to miss some more bats, he'll have a larger margin for error. That makes him a good sleeper, particularly because he is going to soak up a lot of innings for the Rockies, but he's not someone on whom you should be relying heading into the season.

The Quick Opinion: To say that Chatwood's successful 2013 season came out of nowhere would be an understatement. And while it would be folly to bank on him being just as good in 2014 as he was in 2013, he is definitely an interesting sleeper pick in deeper leagues.
